I think it would be great if CR could standardize how they go about tagging shows. As it is searching for shows by genre is hit or miss, there are many shows that are part of a genre that are not tagged as such.

Sword Art Online is definitely part of the Romance genre, however is does not have a romance tag. The same for A Bridge To The Starry Skies and 11 eyes which both have plenty of romance, but do not show up in the romance genre search. There are still others.

It seems to me that there is no standard process for tagging shows and there should be one to make searching for shows easier.
